Use a owl_dict to store the list of filters. Cathy Zhang reported that narrowing to filters that reference other filters is significantly slower than narrowing to filters that don't. The culprit is almost certainly the linear lookup of filters by name, which we currently do on each filter evaluation. Switch to using an owl_dict, which will now do a binary search over the filter list. We could potentially get this even faster by caching the owl_filter itself inside the owl_filterelement, and invalidating it somehow on filter redefinition, but we can save that sort of cleverness for later, if necessary. We also store the filters in a linked list, in order to preserve the ability to traverse them in order, for ":show filters" and for coloring.
